I have two male dogs 1 has been neutered(11 year old cross staffie) and the other hasnt (2 year old american bulldog) they have had three fights in the past year over rawhide bones. they do not fight over anything else. The staffie used to be in a pack up until 2006 when sadly my other dog (male) died he has been on his own up until 2010. this dog did not have any previous issues with food guarding, toy guarding etc. but now we have another dog that we have had for a year he snales and growls at him if he comes need his food (doesnt attack). I do take the food off him when he does this but he still has food guarding issues. I dont leave food down for him I only give him the food when he actually wants to eat it. When they have rawhide bones i sit in the room with them until the bones have been consumed, however, i was distracted last week and forgot and there was a fight and the staffie had to see a vet. My question is will I be able to modify the staffies behaviour and how? or would it just be best to give them bones and food in seperate rooms? The staffie is also taking steriods for a severe skin contact allergy.
